Outdoor Fuse Cutout

1. Application:

Drop-out fuse cutout is installed at the high-voltage side of transformer or distribution sub-line. It provides reliable over-current protection for primary distribution systems. Over-current protection safeguards an electric system from excessive currents produced by abnormal conditions such as line faults, line or equipment overloads, or equipment failures. It will provides full range over-current protection from minimum melt of a given fuse link to the maximum nameplate current rating.

2. Service Condition:

I.) Ambient temperature: -40 0C ~ +40 0C

II.) Altitude: up to 1500m above sea level. III.) Maximum wind velocity: 35m/s IV.) Earthquake intensity: 8 degree

3. Operation order:

In normal operation, the fuse tube of cutout is at close position by tightening the fuse link. When fault occurs in system, fault current will make the fuse link melt quickly and create electric arc with much gas and high pressure inside the tube, which will blow vertically along the inside tube to crush out the electric arc by drawing out. When fuse link melt, lower static contact will turn down because of losing tension and lock structure will discharge fuse tube that will drop-out to form a sensitive breaking position. When pull-load is needed, using insulating pole to pull live contact. At that time, main static and live contact still touch together, then pull contacts continuously to separate auxiliary contact, which will create electric arc between auxiliary contacts. The electric arc will be tightened in the arc chute that will produce gas too and crush out the electric arc when the current is below zero.

4. Construction:

This cutout is composed of insulating base, a fuse tube and mounting bracket. Two sides of fuse tube fit with upper and lower contacts. This cutout is available with a 100A or 200A fuseholder. Detail construction please see attached picture:
